depressors in mineral processing

Mineral processing | Metallurgy, Crushing & Grinding

mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and ...

Depressors

DEPRESSORS are reagents, the introduction of which into the flotation process causes a decrease in the extraction of certain minerals. The use of depressors leads to the displacement of the collector from the surface of the mineral and to the creation of conditions that prevent the sorption of the collector.

mineral processing summary | Britannica

mineral processing, or ore dressing, Mechanical treatment of crude ores to separate the valuable mineral s. Mineral processing was at first applied only to ores of precious metals but later came to be used to recover other metals and nonmetallic minerals. It is also used during coal preparation to enrich the value of raw coal.
